Air pollution measurement is the process of collecting and measuring the components of air pollution, notably gases and particulates. The earliest devices used to measure pollution include rain gauges (in studies of acid rain ), Ringelmann charts for measuring smoke , and simple soot and dust collectors known as deposit gauges .

Air pollution forecasting is the application of science and technology to predict the composition of the air pollution in the atmosphere for a given location and time. An algorithm prediction of the pollutant concentrations can be translated into air quality index , same as actual measurements.
Air pollution costs the world economy $5 trillion per year as a result of productivity losses and degraded quality of life. [24] [25] [26] These productivity losses are caused by deaths due to diseases caused by air pollution. One out of ten deaths in 2013 was caused by diseases associated with air pollution and the problem is getting worse.
Air pollution is associated with an estimated 7 million premature deaths each year. WHO guidelines recommend exposure to no more than an annual mean PM2.5 concentration of 5 micrograms per cubic ...
Delhi’s government is exploring a new strategy to tackle the annual problem of toxic air pollution – inducing artificial rain over the national capital.. The Indian capital’s administration ...
Passive sensors detect natural radiation that is emitted or reflected by the object or surrounding area being observed. Reflected sunlight is the most common source of radiation measured by passive sensors and in environmental remote sensing, the sensors used are tuned to specific wavelengths from far infrared through visible light frequencies ...
Environmental chemistry is used by the Environment Agency in England, Natural Resources Wales, the United States Environmental Protection Agency, the Association of Public Analysts, and other environmental agencies and research bodies around the world to detect and identify the nature and source of pollutants. These can include:
Plastic pollutes oceans, food, your body. Yet nations are divided over a global treaty. Why all eyes are on talks for a U.N.-led accord to cut plastic waste.
